Hint:We know that in physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.

By definition, interference is the redistribution of intensity on
account of the superposition of two waves. Interference is of two types : Constructive and destructive interference
When the crest and trough of one wave meet the crest and trough of another wave, respectively, then we say that constructive interference between the waves takes place. Resultant waves have maximum intensity during constructive interference. When the crest of one wave meet the crest and trough of other wave, then we say that destructive interference between the waves
takes place. Resultant waves have minimum intensity during destructive interference.

Hence the correct answer is option C.

Note: There are two types of interference: constructive and destructive. Destructive interference occurs when the wave amplitudes oppose each other, resulting in waves of reduced amplitude. This is what is called Destructive Interference, which is a subfield of the larger study in physics known as wave propagation. An interesting example of this is the loudspeaker. ... These two sounds interfere destructively, muffling the noise of the engine. Another example is in industrial noise control.
